AdFlagger is a B2B brand protection company.

We help brands detect and remove ads, fake domains, affiliate abuse, parasite SEO pages, and other SERP assets that steal branded traffic.

Our core services:

• Ads Removal
• Domain Removal
• Brand SERP Protection

Our main growth segments are digital businesses with high branded search value.

About the role

We are looking for a Head of Growth / Business Development Lead.

This is not a standard Sales Manager role.

We need a hands-on person who can build a predictable B2B lead generation and sales pipeline almost from scratch.

You will be responsible not only for sales calls and proposals, but also for the full growth system around sales: ICP, outbound, LinkedIn outreach, email outreach, CRM, commercial materials, case studies, website lead generation, and coordination with content, SMM, design, and WordPress development.

The key goal is simple: build a system that generates qualified B2B leads, not just wait for inbound requests.

Responsibilities

• Build and manage outbound lead generation.
• Work with existing contact databases.
• Find and qualify new target accounts.
• Run LinkedIn outreach and email outreach.
• Prepare outreach sequences, messages, and follow-ups.
• Manage CRM and keep pipeline data clean.
• Own the sales pipeline from first contact to commercial proposal.
• Conduct discovery calls with potential clients.
• Prepare commercial proposals, presentations and follow-ups.
• Coordinate website lead generation improvements.
• Suggest landing pages, case studies, sales materials, and lead magnets.
• Coordinate SMM, content, designer, and WordPress developer when needed.
• Track qualified leads, pipeline value, conversion rates, and closed revenue.

Requirements

• 3+ years of experience in B2B international sales, business development, or growth.
• Experience with outbound lead generation.
• Ability to build pipeline, not only close inbound leads.
• Experience selling digital services, SaaS, IT services, affiliate/iGaming, marketing, compliance, or similar B2B services.
• Strong English for outreach, calls, and proposals.
• Good CRM discipline.
• Ability to write clear, relevant, non-generic outreach messages.
• Understanding of how website, landing pages, case studies, and sales materials support lead generation.
• Ability to coordinate marketing, design, content, and website-related tasks.
• Ownership mindset.

• Practical approach: ability to plan, execute, test, and improve without waiting for perfect conditions.

   

Nice to have

• Experience in iGaming, affiliate marketing, dating, cybersecurity, fraud prevention, brand protection, legaltech, or compliance.
• Existing network in gambling, affiliate, dating, or digital business.
• Experience with LinkedIn outreach, email outreach, conferences, partnerships, and account-based outreach.
• Experience selling high-ticket B2B services.
• Understanding of branded search, affiliate abuse, fake domains, brand bidding, or SERP-related risks.

• Experience working in small teams where processes are still being built.

   

You are not a fit if

• You only worked with inbound leads.
• You expect ready-made qualified leads from the company.
• You dislike CRM.
• You do not want to be involved in outreach and lead generation.
• You see marketing and sales materials as “not your area”.

• You prefer only closing calls and do not want to build the system.

   

Compensation

Base + performance-based bonus tied to qualified pipeline and closed revenue.

Final compensation depends on seniority, relevant industry experience, and ability to build the growth function, not only perform sales activities.

Hiring process

1. Short screening call.
2. Test task.
3. Final discussion about expectations, compensation, and first 90-day priorities.

4. Offer.

    

Why join us

AdFlagger has a clear service focus, real market pain, and strong potential in several B2B niches.

This role is for someone who wants to build a growth function, not just maintain an existing sales process.

If you know how to create outbound, open new B2B markets, and turn niche services into structured sales opportunities, we would be glad to talk.

About

We are building an AI-native SaaS for real estate. The product is a PropTech SaaS platform where LLMs and AI agents are not bolted on top - they are the architecture. Owners, operators and guests interact with the AI system through natural language. AI autonomously generates compliance documents, routes staff, answers guest queries from RAG-indexed knowledge base in real time and orchestrates financial split-payments.

But the product is only half of it.

We are equally an AI-first engineering organization. The way we build is as differentiated as what we build. Our daily development loop - specification, implementation, code review, testing, deployment, on-call response - should run on a custom orchestrator of coding and operations agents. Human engineers operate at the level of intent, architecture, judgment and review. Agents should do most of the typing.

The role

This is the role that defines how that system works and how we build the product.

This is a hands-on technical leadership role at the core of the company's future, with a single defining characteristic: you will architect both the product development & testing approach and the AI based engineering system that builds it.

You will own the design, construction and operation of an internal AI-first development platform - the orchestrator, the agent fleet, the specification format, the evaluation harness, the CI/CD wiring - that lets a small team of senior humans ship at the velocity and surface area of a larger conventional team. You will decide what the human engineering team does, what agents do.

You will simultaneously own the production AI layer of the product itself - RAG pipelines, agent workflows, prompt strategy, vector memory - because the same intuition that makes the engineering org work makes the product work.

You will write production code daily. You will read agent diffs daily. You will build and tune evals continuously. 

We operate in a fast-moving startup environment where speed and precision both matter. You must be opinionated about which engineering tasks AI does well today, which it does not and how to close that gap inside our codebase deliberately.

What you will own & do

AI-First Engineering System (the differentiator)

• Build and operate the AI-first engineering system: design the orchestrator (task decomposition, agent coordination, review gates, deployment/rollback) and manage a fleet of coding, review, testing, and ops agents.
• Establish a spec-driven development model: convert product intent into machine-readable specs that agents can implement, test, and evolve reliably over time.
• Define governance and trust: set clear boundaries for agent autonomy vs. human approval, implement verification layers (evals, tests, canaries, traces), and codify standards as machine-readable rules.
• Continuously optimize performance and autonomy: run evaluation frameworks (A/B tests, drift detection, cost/latency tracking), make model/infra decisions, and increase the share of SDLC handled autonomously each quarter.

Technical Architecture & Strategy

• Define and own the full technical architecture of the SaaS platform: service boundaries, API design, data models and infrastructure
• Make fast, reasoned architectural trade-offs under startup timelines without accumulating critical technical debt
• Set the technical direction for AI integration in the product: the AI layer is a core product pillar not a feature.

Hands-On Engineering

• Write production-grade code - much of it through and alongside agents, all of it to your standard (stack to be defined).
• Build and maintain frontend interfaces where needed (stack to be defined). Own database design and query performance
• Design and ship real-time systems: live dashboards, event-driven pipelines.

Product AI & LLM Layer

• Own the end-to-end AI layer of the product (from prototype to production): lead adoption of new LLM tools, build and operate RAG pipelines, manage vector databases, and ensure only production-ready solutions are used.
• Design and orchestrate AI workflows and prompt strategies to power core use cases (guest chat, operator briefings, compliance docs, natural-language commands) while continuously evaluating and integrating cutting-edge AI capabilities.

Integration Layer

• At a certain point own the full integration architecture across all third-party systems - IoT platforms, smart locks, payment rails, government and regulatory APIs.
• Ensure the integration layer is reliable, observable and extensible - future integrations include additional regulatory APIs and secondary trading infrastructure.

Engineering Leadership

• Lead a small, high-caliber hybrid team (engineers + AI agents): set technical standards, run code reviews, unblock delivery, and ensure consistent execution under pressure while maintaining high quality.
• Act as the bridge between business and engineering: translate product needs into clear, agent-executable work, build an AI-first engineering culture, and mentor the team on effectively working with AI (what to delegate vs. retain).

Infrastructure & Reliability

• Own and build scalable infrastructure from scratch: set up CI/CD with agent participation, design cost-efficient cloud architecture and ensure production readiness for live operations.
• Implement full observability and reliability practices: monitoring, alerting, agent traceability, cost/latency tracking, API health and an on-call capable system that is transparent and controllable.

What we are looking for

Must have

• 5-7+ years in software engineering, with technical leadership experience of a team under direct supervision.
• Proven 0 → 1 experience - you have built AI first engineering teams, systems and architecture from scratch, not joined an already-scaled org.
• Strong production experience with modern backend ecosystems (TypeScript / Node.js or equivalent) - you can design and evolve service architectures at speed.
• Solid frontend engineering competence (React, Vue.js or equivalent) - enough to architect, review and unblock teams.
• Deep understanding of data layer design (relational databases such as PostgreSQL or equivalent), including multi-tenant architectures, performance and access control models.
• Proven ability to select, evolve and own the technology stack based on product needs, not trends.
• Comfortable working across the full stack when needed — but with clear architectural judgment on trade-offs
• Daily, deep, native use of agentic coding tools on real production codebases - not toy demos. You have shipped meaningful features where the majority of code was agent-authored under your direction.
• Hands-on experience designing or significantly extending an internal AI development workflow - orchestration of multiple agents, spec-to-PR pipelines, automated review, agent-driven test generation, or comparable systems.
• Production experience with LLM/AI integration in user-facing product - RAG pipelines, vector databases, prompt engineering, agent workflows. Features real users rely on, not demo projects.
• Rigorous instinct for evaluation - you treat LLM outputs as something to be measured, not trusted, and you have built evals to prove it.
• Demonstrable track record of integrating multiple complex third-party APIs into a coherent, stable product.
• Experience building real-time systems
• Comfortable setting up CI/CD and cloud infrastructure from zero.
• Advanced English - oral and written.

Strong advantage (Nice to have)

• You have built or open-sourced an agentic dev tool, orchestrator, eval harness or comparable internal-facing system.
• Familiarity with orchestration frameworks and agent observability tooling
• Experience in PropTech, Fintech, hospitality technology or multi-sided marketplace platforms.
• Background with IoT protocols and smart home device ecosystems.
• Experience integrating government or regulatory APIs.
• Familiarity with tokenization infrastructure or regulated fintech architecture.

Why this role

You will simultaneously build the first AI-native operating system for real estate in Dubai and the AI-first engineering org that ships it. Both are differentiators, both are hard and both are yours.

• Genuine architectural ownership - of the product and of the way we build it. This is not a “maintain and improve” role.
• Clear growth trajectory - this role evolves into Head of Engineering and eventually CTO. We are building that succession deliberately.
• Direct access to founders - short decision loops, no middle management, real influence on product direction.
• Technically ambitious surface area - AI agents, RAG, IoT, real-time systems, government API integrations and eventually (later) tokenization infrastructure. All in one product, all built by a system you design.
• Bonuses - we know how to appreciate the hard work. Bonuses will be assigned based on performance at CEO’s discretion.
• Equity participation - at a defined point you will own a share of what you build.
• Great office in the heart of Dubai’s business life - Once Central Plaza

The Role

We're looking for a senior backend engineer to design, build, and own the API platform that powers our biometric identity and payments product. The platform handles real-time device communication, payment processing across multiple providers, KYC verification, and a permission system that spans organizations, roles, and devices.

This is a backend role focused on API design, service architecture, and data modeling. You'll make decisions that shape how the platform scales — choosing service boundaries, designing schemas that hold up under load, and integrating with third parties without coupling our codebase to their failure modes.

You'll also contribute to our Python SDKs and on-premise deployment story, but the core of the role is the API platform itself.

You'll join a small backend team where your decisions shape the architecture.

What You'll Work On

Core — API platform:

• Designing service architecture and database schemas for new domains
• Shipping API features end-to-end: models, endpoints, async workers, admin tooling
• Optimizing PostgreSQL queries and ensuring zero-downtime migrations on a production database
• Building reliable third-party integrations (payments, KYC, SMS) with retries, error handling, and observability
• Maintaining real-time communication via WebSockets between the platform and physical devices
• Code review, testing, and security as a core part of how you work
• Contributing to Python SDKs that external developers integrate against
• Supporting on-premise deployments — packaging, configuration, environment-specific behavior
• Writing technical documentation: API references, integration guides

Tech Stack

• Languages: Python (primary), Go (supporting services)
• Frameworks: Django (core), FastAPI, Flask
• Databases: PostgreSQL, MongoDB, Qdrant, Redis, TimescaleDB
• Auth: JWT, OAuth2
• Infrastructure: Docker, Kubernetes (Helm), GitLab CI/CD, AWS (S3, KMS), Sentry
• Testing: pytest, factory_boy — 75% coverage enforced in CI
• API Documentation: OpenAPI / Swagger

What We're Looking For

You design systems, not just code features. You can take a vague problem — "we need to support a new payment provider," "we need a new permission scope" — and translate it into service boundaries, data models, and integration contracts. You've done this before: schema design, choosing between sync and async paths, knowing when to introduce a queue vs a direct call, and when an integration deserves its own service.

You know PostgreSQL well. Not "I've used the Django ORM." You design indexes for the access patterns you actually have, write migrations that don't lock production tables, read query plans, and recognize an N+1 in review.

You think of the API as a contract. Versioning, error semantics, idempotency, pagination, backward compatibility. Your OpenAPI specs match reality. You design endpoints that are obvious to consume.

You take testing seriously. You write tests that catch real bugs — integration tests against a real database, not mocks that mirror your assumptions. You test permissions, edge cases, and error paths. Test code gets the same care as production code.

You've run background tasks in production. Retries, idempotency, at-least-once delivery, race conditions in distributed workers. Dramatiq or Celery — the concepts transfer.

Code review is engineering, not gatekeeping. You catch N+1s, IDOR vulnerabilities, missing error handling, broken backward compatibility. You give actionable feedback — and accept review on your own code without ego.

Project Description:
Our client is building data- and AI-driven solutions in a cloud-first environment, with a strong focus on GCP, BigQuery, and large-scale data workflows. The current work is centered around exploring and defining new solution directions, especially in voice-related use cases, where architecture decisions must balance feasibility, scalability, and production readiness.
The environment is highly collaborative and cross-functional, bringing together technical leadership, data scientists, and engineering teams to shape complex solutions from early discovery through implementation.

We are hiring a Lead Data Engineer to help define and shape solution architecture for new data- and AI-driven initiatives.
This is an architecture-focused role working on GCP-based systems, big data modeling, and agentic / LLM-oriented solution design, with a strong emphasis on turning ambiguous requirements into clear technical options.
You will work on early-stage solution design, feasibility analysis, production architecture planning, and proof-of-concept preparation. The role is especially relevant for candidates with experience in voice data, call-agent systems, or similar real-time / unstructured data environments.

Responsibilities:

• Evaluate technical feasibility of proposed voice-agentic systems
• Design production-grade solution approaches on GCP, especially around BigQuery
• Work with large, unstructured datasets and define storage / transformation strategies
• Support solution design involving LLMs and agentic workflows
• Prepare architecture documentation and technical recommendations

James Cook Media, Inc. is looking for an Unreal Engine Technical Artist or 3D Artist with strong UE5 skills to compose photorealistic outdoor environments for an internal R&D simulation platform. You will own the visual quality of the project end to end: world building with geospatial terrain streaming and high-fidelity asset libraries, lighting and atmosphere design, asset modeling for in-scene actors, VFX, and the asset pipeline that ties it all together.

This is hands-on production work with strict performance constraints. Photorealism is the goal, but it has to ship within frame budget on consumer hardware. If you enjoy the craft of making real-world locations feel believable while staying disciplined about poly count and draw calls, this role is a good fit.

Engagement

• Type: Project-based contract or part-time
• Location: Remote, Ukraine-based
• Duration: ~3 months with possibility of extension
• Start date: May 15
• Compensation: Competitive, discussed during screening call

What you'll do

• Build photorealistic outdoor environments combining real-world terrain streaming with high-quality close-range asset libraries
• Author multiple lighting and weather presets per scene (clear, overcast, dusk, night) with full control over atmospheric and sky systems
• Model and material a small number of in-scene actors with proper LOD strategy, damage states, and material variants
• Author VFX for environmental effects and in-scene events
• Own the asset pipeline: import workflow, naming conventions, folder structure, LOD policy, texture compression, performance budgets
• Profile and optimize to hit interactive frame rates on consumer-class hardware at 1440p
• Collaborate closely with the engine programmer on integration, the engineering lead on requirements, and tooling team on in-editor authoring helpers

Required skills

• 5+ years of production 3D work in real-time engines, with at least 2 years in Unreal Engine (UE5 specifically preferred)
• Experience in geospatial streaming workflow (Google 3D Tiles, Cesium ion, georeference origin handling) or willingness to ramp up quickly with strong UE5 fundamentals
• Strong UE5 environment art skills - terrain blending, foliage placement, material variants, ground integration of imported assets
• Lighting and atmosphere mastery - dynamic and baked GI, sky and atmosphere systems, post-process, color grading, time-of-day systems
• Good understanding of performance trade-offs - draw calls, overdraw, shader complexity, LOD strategy, virtualized geometry
• VFX authoring at production quality
• Performance profiling with engine tools; ability to diagnose draw call, overdraw, and shader complexity issues
• Asset pipeline discipline: clean folder structure, naming conventions, version control hygiene
• Strong sense of composition and craft - the difference between dropped assets and an intentional scene

Nice to have

• Cesium for Unreal hands-on experience
• Quixel Megascans proficiency including Bridge integration
• Niagara for VFX authoring
• Lumen and Nanite production experience
• TSR and DLSS configuration experience
• Sky Atmosphere, Volumetric Clouds, Exponential Height Fog tuning
• Material authoring beyond defaults (custom shader graphs, layered materials)
• World Position Offset / Pivot Painter for foliage wind effects
• Previous work on simulation, training, or visualization projects (not just games)
• Familiarity with photogrammetry workflows
• Comfort with Blueprint scripting for editor utilities
• Git or Perforce experience

If parts of this stack are new to you but UE5 fundamentals are solid, that is fine - we have a structured ramp-up window in the first phase of the project.
